I say this is for Circuit City because that's where I got mine. Other stores may or may not work.
First, you best hurry, and if your CC thinks to check walmart's website, it's been removed so it probably won't happen.
Here's what I'd recommend:
1) Call your local Circuit City and ask if they price match. Tell them you have a printout of a deal, but lost the original ad. If they say it's fine, head over. If not, see if there's another around or try it anyway.
2) Get your Zune and walk up to the service desk.
3) Tell them you'd like to get a price match and you called in advance to make sure a printout would work. Cashiers usually don't care that much, they don't see a loss in profits. My cashier said stuff like "OH! That's a good deal". Well, no ****.
4) Pay. I'd recommend doing it in cash.
5) Hopefully skip merrily away with a new zune.
Use the following PDF:

Not guaranteed to work, but it's gotten me and two of my friends a new zune 80.
Good luck
EDIT:
I'm being told a lot of CC are saying they would have to verify the deal. Since it's been removed from the website, it'd be a no go.
You can still get by though. The PDF I made is dated yesterday from when the deal was still in existence. Just tell them you haven't checked up on it since then.
Also, Greg says Sears is a possibility.
